Just curious, but can anyone think of a reason why Apple would replace parts of a MacBook Pro's case under AppleCare? I've seen a few on eBay posted with new cases "replaced under warranty" & wonder how this would happen. My MacBook Pro has a few scratches on the bottom caused by one of those damn Speck hardcover cases (protective my ass!!) and would love to think of a reason why it might get fixed under warranty
I would think that it would be because of a manufacture defect or a bad genius messing it up when opening the computer up . As I've had the top case and bottom case both replaced under warranty for seemingly no reason before. Although in your case I can almost guarantee you that they will not replace your bottom casing for that reason. As the damage is caused by you and not from a defect.
